Life-threatening dermatoses in travelers

Life-threatening dermatoses in travelers relates to infections, or allergic or drug reactions. Of the infectious dermatoses, most are parasitic or viral- because of the short time frame. Bacterial infections usually have a longer incubation. More significant are allergic reactions from environmental or dietary causes, and drug reactions, especially those drugs taken for prophylaxis from tropical diseases. All of these can be fulminant and therefore an awareness and early therapeutic intervention is mandatory.
